EDWARD F. KUNATH, or JERSEY CITY, NEW JERSEY, ASSIGNOR TO UNDERWOODTYPEWRITER COMPANY, or N W-roan, N. Y., a

CORPORATION on NEW JERSEY. w i I Ives-emanate MACHINE..-

citizen of the United States, residing in Jersey City, in the county ofHudson and State of New Jersey, have invented certain newand usefulImorovements in Type-Writing Machines, of which the following IS aspecification.

This invention relates to tabulating devices for type-writing and othermachines.

In using ta'bulating mechanism for different kinds of work it iscustomary to readjust the column-stops along the column-stop bar eachtime that a different class of work is to be done, so as to meet thedifferent require: ments, the-columns of one class differing in widthand location from another.

The principal object of my invention is to provide improved means forbringing different sets of column-stops into effective position, so thatwhen it is desired to change from one kind of work to another it will benecessary only to move a finger-piece, whereby the appropriatecolumn-stops will be set for the new kind of work. To this end I providein the preferred form of my invention a single'row or series ofcolumn-stops placed side by side and, if desired, abutting one againstanother and each movable independently'of the others into and out ofworking position. I also provide a bar or barrel extendingalonq theseries of column-stops and having diifefent sets of projections u on itsperiphery. This bar maybe rotate by a finger-piece, so as to cause anyset of its projections to act upon the corresponding column-stops' andmove some of the latter to idle position. Said revoluble bar may haveany desired number of sets of projections thereon, and by rotation ofthe bar any one. of said sets may be brought into use. The sets ofprojections extend along the bar, and all of the projections in each setare brought into use simultaneously.

In the accompanying drawings, in which my invention is shown as appliedto the wellknown Underwood type-writing machine,

Figural is a rear view and Fig. 2 a top view of the usual Underwoodtabulator mechanism provided with my improvements. 'Fig. 7 3 is aperspective view thereof. Fig. 4 is a sectional view showing thetabulator and a v Specification of Letters Patent. Application filed May29, 1905. Serial No. 282,882.

portion of the carriage and carriage-feeding devices.

Upon the usual carriage 1 is mounteda.

rack 2, meshing with a pinion 3,= connected to an escapement-wheel 4.Cooperating with the latter are the usual dogs 5, operated by thefinger-keys. (Not shown.) Upon the carriage, which as usual ispower-driven, is fixed the usual stop 6, which cooperates with theseveral column-stops to arrest the released carriage in the properposition to bev gin writing inthe desired column.

In place of this stop may be substituted any suitable set ofdenomination-stops, and it will also be understood that within the scopeof my invention it is feasible to place the single stop or thedenomination-stops upon the machineframe and tomount the column-stopswith their appurtenances upon the carriage.

The column-stops are designated as 7 and are pivoted side by side upon acylindrical rod 8, so that any stop may turn independently of the otherstops. Said rod 8 is fixed at its ends in a pair of rock-arms 9 10,whose upper ends are joined by a rack-bar 11, and the lower ends by asquare rock-shaft 12, said bar and rock-shaft forming arigid'frame whichis hinged at 13 upon the framework 14 of the machine. 15 to engage theteeth of the rack 11, thereby preventing displacement of thecolumn-stops along the rod. It will be'seen that the principal portionof the space between the arms 9 10 is occupied by the column-stops, somethirty being shown within the space of about Each ofsaid stops hasteeth.

nineinches and these being sufliciently numerous for practical purposes,although more can be assembled within the same space, if required, bymaking each one thinner. A spring 16 tends normally to hold the teeth 15upon each stopin engagement with the rack 1 1, said spring being mountedwithin a recess in the stop and pressing down a ball or round plunger16, the latter engaging a groove 17,

which extends longitudinally of the rod 8.

The rod is also provided with a longitudinal groove 18 back of thegroove 17, so that any stop may be swung we. back by means of a handle19 and thereshe d by the engagement of the spring-ball with the groove18..

Along the single row of stops extends a ba 20, which is revolublymounted in bearings-f 20* and 20 fixed upon the rock-arms 9 10. Said barhas four sets of projections, each extending longitudinally of the bar,and the sets being numbered respectively 21, 22, 23, and

' 24. The projections in each set are adapted to strike down upon thehandles or projections 19 of thestops and vibrate ,the latter rearwardlyupon the rod 8 into idle position. Only those stops which are notoperated by said projections upon the bar 20 are left in' otherwiseformed, and either less or more than four sets of stops may be used.

Upon the end of the bar 20 is fixed afingerpiece or. wheel 25, which isprovided with numbers, as seen at Figs. 1 and 2, to indicate to theoperator which set of projections, an d hence which set of column-stops,is in use. If desired, an index 26 may be fixed upon the machine topoint to the numbers upon the wheel 25.

In use the revoluble bar 20 is turned to the left at Fig. 4 to bear downthe handles 19 of the stops that are not wanted, while all other stopsare moved or held up in working position by their springs 16. The baralways turns in the same direction in shifting from one set of sets toanother. The parts are so proportioned that the handles19 escape thelower stops when they are just past the position occupied by 24 at Fig.4;, thus permitting the springs 16 to lift the stops to effectiveposition. It will be seen that the lower pro ections 24 are in use,since they hold down the handles 19 upon some of the stops, while by aslight turn to the left the depressed handles 19 are released and moveup, while the same or other handles are carried down by the succeedingset of stops 21. The operator needs only to revolve the finger-wheel 25until the desired number thereon is brought into view or comes oppositethe index 26.

Upon the left-hand end of the bar at Fig. 2 is formed a square shoulder27, which is received by a recess 28, formed in the bearing member 20*,whereby revolution of the bar 20 isprevented, and the projections, as24,

p are enabled to hold down the handles 19 against the tensionof thesprings 16. In order to release the bar, it is moved sidewise to theright at Fig. 3 by pressingupon the finger-piece 25, whereby theshoulder is Withdrawn from the recess 28. The bar is then rotated andwhen the desired number comes opposite the index 26 thebar is releasedand a (-01I'IPIPSSlOll-SPI'lHQ 22-), secured to the bar. presses thesame to the left until the shoulder 27 a ain enters the recesses,thereby holding the ar fixed with the set of projections 21v holdingdown the corresponding handles 19. Thus any ofthe four or more sets ofprojections may be brought into use merely by turnin the finger-piece25, without the necessity of readjusting the column-stops along the rodas heretofore.

It will be understood that the teeth 15 upon the-stops are sufficientlylong to remain in engag ment with the rack 11 during the rotation f the.bar 20; but when desired any of the stops may be swung back until saidteeth spring-balI 1'6 enters the groove 18. Thus one or more of thestops may be swung out of use and out .of control of the bar 20, andsome range of said bar, as at C, or in some cases may be adjusted alongthe .bar, if desired.

The type-keys are manipulated in the usual manner and the tabulating key30 is depressed and acts upon a link 31, connected to an arm 30 upon therock-shaft 12, thereby rocking the column-stop frame forwardly until theactive column st ops in position A are brought into the path of the stop6 upon the carriage. Upon the shaft 12 is fixed an arm 32, which actsupon a lever. 33 to lift the carriage-rack 2 out of engagement with thepinion 3, so that the carriage maybe drawn along rapidly by its spring.

Variations may be resorted towithin the improvements may be used withoutothers.
